From 20ee2bf138323c6688b6e8d71d695cf2bd53f857 Mon Sep 17 00:00:00 2001 From: Todd Short Date: Thu, 16 Feb 2017 16:08:02 -0500 Subject: Fix time offset calculation. ASN1_GENERALIZEDTIME and ASN1_UTCTIME may be specified using offsets, even though that's not supported within certificates. To convert the offset time back to GMT, the offsets are supposed to be subtracted, not added. e.g. 1759-0500 == 2359+0100 == 2259Z.
